Is it alright ?
Sigh...
RudiC has told you two times now to separate the two asterisks by a space. The line as you present it is still wrong because of that and no matter what options to tar you try will change anything about that BECAUSE THIS IS NOT THE PROBLEM IN FIRST PLACE!
Try a layered approach: first, consult the man pages of cron and learn how to configure a (any) command to be run by cron. Only then concern yourself with constructing the correct tar-command: first manually. When it finally does what you want it to do put it into cron using your new-found expertise on creating cron-jobs.
So much as a starter: cron jobs have NOT the same environment as commands run from an interactive session, namely the PATH variable is empty and therefore you should use full pathnames. instead of tar <cmd> /some/path you need to write something like /usr/bin/tar <cmd> /some/path. Notice the full path to the command. Your path might differ, but you can easily get the (on your system) correct path with the which command:

Hi All,
Is there is any way to find the size of compressed file without doing decompression. The size should give the original uncompressed data size
Thanks

BF_TAR(1) Bogofilter Reference Manual BF_TAR(1)NAME
bf_tar - shell script to write a tar file of a bogofilter directory to stdout
SYNOPSIS
bf_tar [-r] [-R] bogofilter_directory
DESCRIPTION
bf_tar bundles a bogofilter working directory in tar format and copies it to standard output (your console, or where you redirect it, see
EXAMPLES below).
OPTIONS
The -r option causes bf_tar to remove inactive log files after the archive has been written successfully. The default is to leave log
files.
The -R option causes bf_tar to remove inactive log files before the archive is written. This may reduce chances that the resulting archive
is recoverable should it become damaged. The archive may be smaller though. The default is to leave log files.
EXIT STATUS
The script exits with status code 0 if everything went well, and nonzero if it encountered trouble.
EXAMPLES
o bf_tar ~/.bogofilter > outfile.tar
Writes a standard .tar file containing the essential files from ~/.bogofilter to outfile.tar.
o bf_tar ~/.bogofilter | gzip -9 -c > outfile.tar.gz
Writes a gzipped .tar.gz file containing the essential files from ~/.bogofilter to outfile.tar.gz.
o bf_tar `pwd`/mydirectory > outfile.tar
Prepend $(pwd)/ or `pwd`/ if you want to specify an absolute path instead of a relative path.
NOTES
This script is meant for use with Berkeley DB based bogofilter versions.
This script requires a SUSv2 compliant pax utility.
This script expects a SUSv2 compliant shell. Solaris systems should have the SUNWxcu4 package installed (when bogofilter is configured) so
that /usr/xpg4/bin/sh can be used.
